Perpetual grow setup

I have a 32x32x60 grow tent for mothers and imma get a 32x60x80 for flowing sog style. I use a lung room but I may vent outside depending on heat but it’s cold here now so may be an issue. I can to have my humidifier in my mother tent set to around 60 the have it vent to the flower tent along with passive air vents to flower tent with a dehumidifier and 4 in exhaust. Any ideas or thoughts?

Or should I just vent both into lung room separately with humidifier in veg with dehumidifier in flower? I plan to swap my 150w driver in veg tent to a dimmable one so heat won’t be bad. Plus winter is here
